This invention relates to windows and more particularly to an improvedweather strip and sash construction.

An object of the invention is to provide a simple, practical andinexpensive weather strip of the character described.

Another object is to provide an improved sash mounting and lock.

Other objects and advantages will appear and be brought out more fullyin the following specification, reference being had to the accompanyingdrawing wherein Fig. i is an elevation view of a portion of the windowillustrating my invention and Fig. 2 is a sectional view taken along theline 2-2 of Fig. 1 and Fig. 3 is a sectional view taken along the line3-3 of Fig. -1 and Fig. 4 is a sectional view taken along the line 4-4of Fig. 1.

Referring more particularly to the drawing, I show a window having ,aside frame 5, stool 8, upper jamb I and sill 8. The Weatherstrip 8,-comprising an important feature of my invention, is secured in anysuitable manner to side frame 5 in a rectangular recess Ill therein.Upper lamb I is provided with a similar recess I! and lower Jamb 6likewise has a recess l2. Weather strip 8 has a pair of grooves l3forming a0 a somewhat wedge shaped strip ll to which is secured asubstantially U-shaped spring member IS. {The windows comprise glass It,the side edges of which extend into grooves l8 and are pressed againstthe outer edges thereof by springs IS. The extreme upper and lower edgesof the window glass It are secured to grooved metallic members l'l,having inwardly curved portions l8 adapted for raising and lowering ofthe windows, the members l1 being adapted to fit closely in recesses IIand I2. The meeting edges of the windows are secured in channel membersl9 and 20, member l8 having a grooved bead 2| and member 20 having'interfitting tongue 22. A lock pin 23 is slidable laterally 5 inapertures 24 in member 20 and has a ring shoulder 25 by which it isbiased in the locked and unlocked positions by spring 28, a suitablehand piece 21 is provided for pin 23, the forward end of which passesunder a portion of head 2| 5 to effect the locking of the windows. Theglass I6 is preferably held in position in the channel members by corkribbon but it will be understood that it may be secured in the channelportions of numbers [1, l9 and 20 in any suitable manner as by cementingwith or without a fabric 5 or resilient element auxiliary thereto. Itmay be desirable in certain cases to provide window panels smaller thanthe normal window opening and in these cases the auxiliary channelmembers 28 are used. 10

By the foregoing description, it will be apparent that I have provided avery efiective weather strip and window mounting which is simple andeconomical to construct and very effective in providing a substantiallyairtight 15 mounting. The sash as described will preferably of aluminumand stainless steel and will never require painting and will berustproof. The sash as described will not require counter sets as muchof the tension of the spring strips 20 It can be adjusted to hold theglass without them. The glass mounted as described, obviates the use ofputty which frequently works loose.

Having described my invention what I claim 25 is e 1. The combinationwith a window frame having'opposed guides, each guide being formed withtwo parallel grooves having their adjacent faces extending at an angleand forming a dovetail partition between the grooves, a resilient striphaving a dovetail shaped grooved fitting the dovetail partition andhaving outwardly extending sides, and panes of glass sliding in saidparallel grooves between the straight walls thereof and said outwardlyextending sides.

2. The combination with a window frame having opposed recesses eachopening at one edge of the window frame, guides in said recesses andformed with two parallel grooves having their 40 addacent facesextending at an angle forming a dovetail partition between the grooves;and a resilient strip having a dovetail groove fitting the dovetailpartition and having outwardly and in-' wardlycurved sides, and panes ofglass sliding 45 in said parallel grooves between the straight wallsthereof and said curved sides of the resilient strip.
